The happy couple attended the House Of The Dragon premiere in London and in photos, Chelsea Menna can be seen wearing a gorgeous ring on THAT finger.
Gold band? Huge rock? Luke did well.
Here's a closer look at the ring...
Okay you can't see much but stay tuned we'll keep you posted.
Luke shared photos from the event on his Instagram account and lots of his followers were quick to comment with fellow Islander Nas Majeed writing, "🔥🔥🔥".
Another person commented, "You both look stunning".
Someone else said, "Hot couple 🔥".
A fourth fan added, "Holy hell who is that absolute babe!!!!!".
The pair's first red carpet appearance comes after Luke's ex Siânnise Fudge updated fans after reports first surfaced that her Love Island ex is engaged to Australian journalist Chelsea following a whirlwind romance.
Taking to Instagram, Siânnise, who is enjoying single life, shared a snap of herself grabbing some probably much-needed cocktails with her pals.
Luke and Siânnise rose to fame on the first ever winter edition of the ITV2 dating show two years ago and finished in second place. Their relationship seemed to go from strength-to-strength in the outside world after they moved into a swanky London apartment together and got an adorable pet pooch, but rumours they had split began swirling late last year after she posted about “ignoring red flags” and “getting through a break-up”.
While Siânnise is thought to have stayed single – after denying she was dating model Chris Beviere – Luke only recently went Instagram official with Chelsea and shortly after it was claimed that they’ve taken a huge step in their relationship after he popped the question.
“It was love at first sight with Luke and Chelsea,” a source told MailOnline.
“Their romance blossomed overnight into a serious relationship and although it's not been long, they both know they're the one for each other.
“Luke has made London feel like home for Chelsea who's from Australia and they're very happy together.”
Luke’s representatives have been contacted for comment.
Before their red carpet appearance, Luke and Chelsea never officially confirmed their relationship but a brief glance at the pair's Instagram profiles certainly hinted at their romance. We've had a close peruse at Chelsea's Instagram Stories highlights and she seems to have set up a new highlight called '🤍' which is full of lovey-dovey snaps of her and Luke (including one of the couple kissing and holding hands).
Luke's followers jumped to the same conclusion we had, with countless fans commenting on his most Instagram post, congratulating him and Chelsea.
One fan commented, "Surely the luckiest man on earth @_chelseakate 🔥."
Another wrote, "Happy for you 😍😍."
Another commented, "Stunning girlfriend 🔥🔥🔥."
The popular Love Island star fuelled rumours that he had moved on from his break-up with co-star Siânnise Fudge earlier this year.
Taking to his Instagram story, Luke shared a snap of himself being carried by a very strong lady - who we THINK is Chelsea - in the gym with the caption, “Strong like ox".
Luke is believed to have split from Love Island's Siannise in late 2021 after just over a year together.
The heartthrob has never addressed the split publicly, but he’s had something of a post-break up glow up, as he’s been hitting the gym and experimenting with his hair: shaving it off and dying it bright pink and bleach blonde. The goatee is doing things to us too, we're not going to lie.
Siânnise revealed that she was officially single after she was asked if the rumours that she had moved on from Luke with model Chris Beviere were true.
Taking to Instagram, she said, "No I don’t have a new boyfriend & I’m currently not dating. I can’t control what people post or write about me but what I can control is how I respond. Unless it’s come from my mouth or I have publicly posted/announced something regarding me having a new boyfriend, then I am very much single & I’m content with that right now."
Siânnise was also recently asked if she was still in contact with anyone from Love Island, to which she replied, "No, I'm actually not! There's no reason for it, I'd always say hi & catch up if I saw anyone from my season but everyone's got their own thing going on and I think lockdown made us all drift. I wish them all well regardless 🖤."

After a few pies and a brief snog with Demi Jones, Nas got his Love Island wish granted when he walked in Casa Amor and met Eva Zapico.
